| Scenario | Piers | Avg Depth (ft) | Weight/ft (lb) | Steel Rate ($/lb) | Labor Rate ($/hr) | Equip Days |
|---|---|---|---|---|---|---|
| Small retrofit crawlspace | 6 | 14 | 7.2 | 1.65 | 52 | 1.5 |
| Typical residential stabilization | 10 | 18 | 8.5 | 1.75 | 55 | 2.0 |
| Heavy access constraints | 14 | 22 | 9.8 | 1.90 | 62 | 3.0 |
Steel Weight (lb) = Piers × Avg Depth (ft) × Steel Weight per ft (lb/ft) × Type Factor
Direct Subtotal = Steel Material + Caps + Brackets + Welding + Labor + Equipment + Mobilization + Permits + Engineering + Site Prep + Disposal + Misc
Overhead = Direct Subtotal × Overhead %
Profit = Direct Subtotal × Profit %
Contingency = (Direct Subtotal + Overhead + Profit) × Contingency %
Grand Total = Direct Subtotal + Overhead + Profit + Contingency + Tax
Steel pier estimates become reliable when quantities and production assumptions are consistent. Start with a clear pier count, an average installed depth, and the exact steel section weight from your supplier. The calculator converts those quantities into total steel weight and material cost, then layers labor, equipment, and allowances to mirror real bid structure.
Labor hours per pier are most sensitive to access, obstructions, and verification requirements. Tight crawlspaces, interior floor protection, hand-carry material, and limited jack stroke typically increase hours and reduce efficiency. Use the crew efficiency field to represent difficult working conditions without rewriting your baseline hour assumptions.
Caps, brackets, adapters, and field fit-up often represent a meaningful portion of the total. If brackets require welding or drilling, reflect that with welding hours and rate. Separating welding from general installation time helps you align specialty labor with the correct burden and pricing, especially when subcontracted.
Apply overhead and profit to the direct subtotal to match your estimating policy, then use contingency to cover uncertainty such as soil refusal depth, hidden utilities, and inspection delays. The tax option lets you model materials-only tax jurisdictions or fully taxable scopes, supporting clearer client proposals and internal approvals.
Example inputs: 10 piers, 18 ft depth, push pier, 8.5 lb/ft, $1.75/lb steel, 2.25 labor hours/pier at $55/hr, 2 equipment days at $350/day, $250 mobilization, $150 permits, $200 site prep, 10% overhead, 12% profit, 5% contingency.
What to check: total steel weight, labor hours, and the line-item breakdown. If the unit cost seems high, test access assumptions first, then verify section weight and accessory quantities before adjusting profit or contingency.
It is the section weight of the pier shaft or casing in pounds per linear foot. Use manufacturer data or mill certificates for the closest match to your specified diameter and thickness.
Use a baseline from past jobs, then adjust for access, protection, verification, and obstructions. If conditions are difficult, lower the efficiency percentage instead of inflating every input line.
Welding often has different crew rates, productivity, and consumable costs. Separating it helps you price specialty work accurately and prevents double-counting when a subcontractor performs connections.
It applies a practical factor to reflect typical differences in steel quantity and effort across common systems. Keep your own section weights and labor assumptions primary for the most accurate bids.
Many firms apply overhead and profit to the direct subtotal, then add contingency to the marked-up amount. This calculator follows that approach, but you can reduce contingency if your policy differs.
Choose whether tax applies to materials only, the full taxable scope, or none. Then enter the local rate. Use contract language and jurisdiction rules to decide what is taxable.
Yes. For budgeting, use conservative hours and contingency. For bidding, use measured quantities, verified section weights, and realistic equipment days. Save the CSV/PDF outputs for review and documentation.
